When it comes to maintaining your Royal Enfield motorcycle, one of the most critical aspects is choosing the right engine oil. The engine oil plays a vital role in lubricating the engine, preventing wear and tear, and ensuring optimal performance. However, with numerous options available in the market, selecting the best engine oil for your Royal Enfield can be a daunting task. In this comprehensive guide, we will delve into the world of engine oils, exploring the various types, factors to consider, and recommendations for the best engine oils for Royal Enfield motorcycles.

Types of Engine Oils
Engine oils can be broadly classified into two categories: mineral-based and synthetic-based. Mineral-based oils are derived from crude oil and are the most common type of engine oil. They are cost-effective and widely available but may not provide the best performance in extreme temperatures.
Synthetic-based oils, on the other hand, are man-made and offer superior performance in extreme temperatures. They provide better lubrication, fuel efficiency, and engine protection. However, they are more expensive than mineral-based oils.
Viscosity and Viscosity Index
Engine oil viscosity refers to its thickness and flowability. Thicker oils provide better lubrication but may increase engine drag, while thinner oils may not provide sufficient lubrication. Viscosity index is a measure of an oil’s ability to maintain its viscosity in extreme temperatures.
The American Petroleum Institute (API) and the International Council on Clean Transportation (ICCT) have established standards for engine oil viscosity. The most common viscosities for Royal Enfield motorcycles are 10W-30, 10W-40, and 20W-50.

| API Certification | Description |
|---|---|
| API SN | Meets the latest standards for gasoline engines |
| API SN PLUS | Meets the latest standards for gasoline engines with improved fuel efficiency |
